Abstract

A hammer drill (1) is equipped with a connector shaft (60), which is rotationally driven by a motor (2), a spindle (7) that transmits the rotation through the connector shaft (60), and a percussive impact means (80) that applies a percussive force in the axial direction to a drill bit held by the spindle (7) through performing a reciprocating motion, in the axial direction, relative to a spindle (7) that receives the rotation of the connector shaft (60) through a motion converter member. The hammer drill (1) is provided with a percussive force converter means from the percussive impact means (80) by changing the speed reduction ratio between the motor (2) and the connector shaft (60). This makes it possible to adjust the percussive force according to the drill bit used. <IMAGE>
